passionne56 Posted February 18, 2023 Share Posted February 18, 2023 Kingston M-die 5600 overclocked to 6400 1T with tight timings and 1.44 V, stable. Happy with this result. I tested 7000 with loose timings but it requested too much voltage. Now, I am waiting for a green chinese A-die kit, ordered a few days ago.

asdkj1740 Posted February 22, 2023 Share Posted February 22, 2023 how to control / set a specific value for rtl?? i cant even copy the rtl values read by asrock timing configurator in bios rtl settings, it just wont boot up. Quote Link to comment Share on other sites More sharing options...
sergmann Posted February 22, 2023 Author Share Posted February 22, 2023 It’s not possible to enter RTL’s manually. If your RTL’s are too high, please set “Round Trip Latency” to “Enabled” after it your RTL’s are tight. Quote Link to comment Share on other sites More sharing options...
spit051261 Posted February 22, 2023 Share Posted February 22, 2023 (edited) Be nice if this board was even available , Z790 I mean ? Managed to get a KP Z790 over 2 months ago but this Tachyon Z790 is still not available . Wonder why ?

sergmann Posted February 22, 2023 Author Share Posted February 22, 2023 Have you played with Round trip latency? I’ve never seen that RTL’s are different after reboot without changing something in Mem-settings. lower CL value is connected to RTL’s and also depends on Mem frequency. If you want higher RTL’s, disable round trip latency in memory training area and don’t leave it with “auto” settings 1 Quote Link to comment Share on other sites More sharing options...

passionne56 Posted February 24, 2023 Share Posted February 24, 2023 (edited) I received a 32 GB Gskill DDR5-6600 Hynix A-die kit, removed the heatspreaders and cooled the RAM with a 140 mm fan. The stability is not permanent : With the X6h bios, I did not manage to obtain stability at 7200 Mhz. I flashed the motherboard with the F23a bios and managed to achieve stability at this frequency, validated with OCCT during 30 min. Then, I managed to be stable at 7600 Mhz still validated with OCCT during 46 min. OCCT is a reliable torture test and after such a long time, I am stable. After a few hours, I did OCCT again and many errors appeared after a few minutes (less than 10 min). I checked the parameters in the bios and tREFI was completely different than the value which brought me stability : above 70000 instead of 6435. I corrected the value by entering 6435, rebooted, entered in the bios again and the tREFi value did not change ! I switched off the PC, switched it on and in the bios, 6435 was applied for tREFi. I then checked stability again with OCCT but crash again after only a few minutes. Since the ambient temperature was not much higher (1-2°C higher), I flashed the F23a bios again, reloaded the 7600 profile which was validated as stable but again, OCCT fails after a few minutes whereas I was stable on this test during 46 min ! I don' t understand why I am not stable any longer : after 46 min without any errors on OCCT, I shouldn't obtain a crash after a few minutes of OCCT : this tool is reliable according to my experience (used since many years). May the training stage change values even if no parameter is modified in bios ? I see only this explanation.

sergmann Posted February 24, 2023 Author Share Posted February 24, 2023 For stability are many things important. For example voltages. If you have it @“auto” check you stable voltages with Hwinfo and set it manually in bios. Same is also necessary for timings. This low tREFi you have only after loading setup defaults. Different CPU’s and Mem need different voltage/timings settings. Sometimes are lower voltages for SA/CPU_VDD/CPU_VDDQ better for Mem OC ?

passionne56 Posted February 26, 2023 Share Posted February 26, 2023 Finally, I am stable at 7600 Mhz. I entered every timing except for the round trip latency. I would like to flash my parameters into the user XMP memory profile : I don't find where I can do that in the bios. And can Gskill memory be flashed ? I had a Kingston kit before and I was able to flash my memory profile into the XMP user one, on a MSI motherboard. Quote Link to comment Share on other sites More sharing options...

sergmann Posted March 2, 2023 Author Share Posted March 2, 2023 It works but I also wasn’t able to go over 9100, import are timings and voltages. If Mem VDD and VDDQ are to high, system don’t start Quote Link to comment Share on other sites More sharing options...

passionne56 Posted March 28, 2023 Share Posted March 28, 2023 (edited) The motherboard behaviour is erratic : I use Memtest86+ to find the voltages and the timings at 8000 MT/s on my 2x16 GB 5600 Klevv kit and I rely on the Memtest errors number to find the best parameters. Many times, with the same parameters, the result can be completely different : 4 errors on the whole Memtest86+ tests on one run and on another one, many errors. I reflashed the bios x6o since I suspected a bios corruption but same result. In order to remove this erratic behaviour, I adjusted every memory parameter except the 2 round trip latency ones : when I enter values on Round Trip Latency(CONA/DIMM0/Rank0) and Round Trip Latency(CONB/DIMM0/Rank0) parameters, I always fail to boot. The parameters I entered are the same chosen by the motherboard (64). I disabled the round trip latency training but I cannot boot. Consequently, my questions : - how to remove this erratic motherboard behaviour ? - why Round Trip Latency(CONA/DIMM0/Rank0) and Round Trip Latency(CONB/DIMM0/Rank0) prevent me to boot ?

Consequently, my questions : - how to remove this erratic motherboard behaviour ? - why Round Trip Latency(CONA/DIMM0/Rank0) and Round Trip Latency(CONB/DIMM0/Rank0) prevent me to boot ? since a few versions of intel chips it`s not longer possible to adjust RTL`s manually in memory settings. Only with different CL and frequency it´s more or less adjustable. For example, CL32 and 8k on mem you will get 59/60 or 60/60 RTL`s als long as you have activated RoundTripLatency in memory training options. In this case you`ll get tight RTL`s automatically And yes, it`s sometimes very hard to get 100% stable frequency for mem, because each board, cpu and mem are different. also cooling is important. As soon your memory will be warmer as before, settings are not stable. For stability is also sometimes necessary to adjust a little bit VCINN and the third VPP A0 voltages. 0,02v more are sometimes very helpfull Quote Link to comment Share on other sites More sharing options...
passionne56 Posted March 30, 2023 Share Posted March 30, 2023 OK, thank you. I came back to 7800 and I am optimizing the timings. Afterwards, I may try 8000 MT/s again with your advice. 1 Quote Link to comment Share on other sites More sharing options...
